Early urodynamic findings after complete primary repair of exstrophy. J Pediatr Urol 2023; 19:565.e1-565.e5. [PMID: 37355344 DOI: 10.1016/j.jpurol.2023.05.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 05/25/2023] [Accepted: 05/29/2023] [Indexed: 06/26/2023]
Abstract
INTRODUCTION Detrusor contraction in bladder exstrophy (BE) patients following reconstruction is poorly understood as there are few published studies assessing urodynamic findings in this population. Understanding the ability of the detrusor to contract in BE patients early after closure may be able to inform the longer-term management and potential for the development of future continence in this population. OBJECTIVE We sought to evaluate early detrusor contraction using urodynamic studies (UDS) in children who had previously undergone complete primary repair of bladder exstrophy (CPRE). We hypothesized that a majority of children with BE would display the presence of normal detrusor contractile function after CPRE. STUDY DESIGN A retrospective review of our prospectively collected database was performed for all patients with a diagnosis of classic BE who underwent primary CPRE between 2013 and 2017. From this cohort we identified patients with at least one post-operative UDS at 3 years of age or older who had undergone an initial CPRE. Our primary outcome was the presence of a detrusor contraction demonstrated on UDS. RESULTS There were 50 children (31 male, 19 female) with CBE who underwent CPRE between 2013 and 2017.There were 26 (13 male, 13 female) who met inclusion criteria. Median age was 3.5 (IQR: 3.2-4.7) years at the time of UDS Sixteen of the 26 (61.5%) generated a sustained detrusor contraction generating a void, with a median peak voiding pressure of 38 cm H20 (IQR: 28-51). The median bladder capacity reached was 48 ml, which represented a median of 30% of expected bladder capacity. The median post void residual (PVR) for the entire cohort was 26 ml (IQR: 9, 47) or 51% (IQR: 20%-98%) of their actual bladder capacity, while the median PVR for those children with a sustained detrusor contraction was 18 ml (IQR: 5, 46) or 33% (IQR: 27%, 98%) of their actual bladder capacity. Intraoperative bladder width and bladder dome to bladder neck length did not correlate with the presence of voiding via a detrusor contraction (p = 0.64). DISCUSSION We present the first study assessing early UDS finding of detrusor contraction in BE patients after CPRE. In our cohort, 61.5% of patients were able to generate a sustained detrusor contraction on UDS which is a higher percentage than has been reported in previous series. A difference in initial surgical management may account for these findings. CONCLUSION At short term follow up, the majority of children in our cohort were able to produce sustained detrusor contractions sufficient to generate a void per urethra with a modest post void residual volume. Long-term follow-up and repeated UDS will be needed to track detrusor contractility rates, bladder capacities, compliance, post void residuals and ultimately continence rates over time.

Abstract
AIMS The International Consultation on Incontinence has published an update of the recommendations for the diagnosis and management of urine incontinence (ICI2016). This manuscript summarizes the consultations committee-recommendations with regard to urodynamic assessment. METHODS Expert consensus on the basis of structured evidence assessment has been the basis of the consultations publication and has been summarized by the committee for this manuscript. RESULTS Patients that are not satisfied with their initial management on the basis of their reported signs and symptoms of urinary incontinence, as well as all patients with neurological abnormalities that are potentially relevant for the function of the lower urinary tract, may very likely profit from objective diagnosis and staging and grading of their dysfunction, with urodynamic testing, regardless their age, vulnerability and/or comorbidities. The principles and technical innovations as well as the principal recommendations for the utilization of (invasive) urodynamic assessment for women, men, children, and vulnerable elderly, with or without neurogenic lower urinary tract dysfunction with urinary incontinence are provided in this abbreviated ICI recommendations-document. CONCLUSIONS The ICI2016 committee on urodynamics presents an executive summary of the most important reasons and recommendations for the use of urodynamic investigations for patients with urinary incontinence.

Abstract
OBJECTIVES Primary female epispadias encompasses a spectrum of disease, presenting with a variable degree of incontinence. We hypothesized that although perineal urethrocervicoplasty can be a successful first-line procedure in patients with normal bladder, a more radical reconstruction was necessary to achieve continence in cases lying at the most severe end of the spectrum. Our aim was to assess the results of a surgical management using perineal approach in girls with normal bladder capacity, and Kelly radical soft-tissue mobilization (RSTM) in patients with inadequate bladder, based on the assumption that bladder capacity (BC) is a reliable marker of epispadias severity. STUDY DESIGN Prospective inclusion of incontinent girls with female epispadias referred to a single institution. Patients with normal BC were treated with perineal urethrocervicoplasty (PUCP, group 1). Patients with small bladder underwent RSTM (group 2). Follow-up was at 1, 3, 6, and 12 months postoperatively, then annually, including physical examination, renal ultrasound at each visit, continence status, and estimation of functional/maximal BC. The main study outcome was continence status at the age of 5 years or later, if postoperative follow-up was >12 months. RESULTS From 2006 to 2017, 16 consecutive children were prospectively included in this study, at a median age of 39 months (5-102 months). Seven girls were included in group 1 and underwent PUCP; at the last follow-up, five out of seven were dry by day (4/5 day and night), although three out of five required bladder-neck injection after perineal reconstruction due to stress incontinence. Two patients with persistent incontinence and absence of BC increase after PUCP subsequently underwent RSTM. Eleven patients with low BC (56% [10-94%] of expected BC) were included in group 2 (9 without prior surgery, 2 after PUCP failure). Among the eight evaluable patients, eight out of eight achieved diurnal continence, and 3/8 were fully continent. One girl with obstructive micturition required clean intermittent catheterization. DISCUSSION The traditional approach of female epispadias based on staged reconstruction (urethroplasty followed by bladder-neck reconstruction) raised concerns regarding the risk of non-physiological obstructive micturition. The perineal approach was suggested as an alternative, with reported diurnal continence rates of 60-80%, but less than 50% of nocturnal continence, presumably in relation with limited bladder capacity. In cases selected within the most severe end of the epispadias spectrum, the Kelly RSTM seems to offer excellent continence rates. CONCLUSION A tailored approach to female epispadias, based on perineal reconstruction in favorable cases, and radical soft-tissue mobilization in severe cases, seems to yield good continence outcomes in the long term.

Sub-urothelial polyp enucleation resection and urothelial auto-augmentation cystoplasty: a simple method for bladder exstrophy-epispadias complex reconstruction in bladder plate polyposis. Pediatr Surg Int 2014; 30:669-76.

Abstract
OBJECTIVES To report the results of a novel technique of sub-urothelial polyp enucleation resection (SUPER) and urothelial auto-augmentation cystoplasty (UAAC) in patients with bladder exstrophy and polyposis plate. METHODS Twenty-eight patients with bladder exstrophy covered by plate polyposis were referred for further management. From these, 12 patients had undergone SUPER, UAAC technique, and subsequent bladder closure. In this technique, the urothelium covering the polyps was utilized as tissue for auto-augmentation cystoplasty. Sixteen patients had been operated by simple polyps' excision and bladder closure. Biopsies of polyps were obtained in both groups at the time of closure for pathological evaluations. The bladder plate was measured pre-and post-bladder plate augmentation. The patients were evaluated every 3 months for 1 year and biannually thereafter for urinary continence and social dryness. Dry period of >3 h during the day with or without nocturnal incontinence was defined as social dryness. RESULTS All patients experienced an uneventful postoperative period. No sign of metaplasia or dysplasia was observed in the histological and cystoscopy evaluations. These findings suggest that neither polyp recurrence nor bladder tumor development has occurred in any of the groups. The urinary continence improved significantly in the polyp's urothelial coverage augmentation cystoplasty technique (66.7%), while 31.3% of patients in simple closure technique achieved continence. Significantly higher mean bladder capacity was obtained in the augmentation group (190 ± 38 ml) and (119 ± 21 ml), respectively. Postoperative mild hydronephrosis and vesicoureteral reflux were significantly lower in auto-augmentation technique. CONCLUSION The final clinical outcome of children with bladder exstrophy polyposis is promising. The combined SUPER and UAAC technique is feasible, safe and reproducible option for bladder exstrophy-epispadias complex (BEEC) patients with bladder plate polyposis. However, it will add one supplementary operation to the single or staged bladder reconstruction. These patients may warrant further surveillance with histopathological evaluations during the adult life.

Abstract
The exstrophy-epispadias complex is a rare spectrum of malformations affecting the genitourinary system, anterior abdominal wall, and pelvis. Historically, surgical outcomes were poor in patients with classic bladder exstrophy and cloacal exstrophy, the two more severe presentations. However, modern techniques to repair epispadias, classic bladder exstrophy, and cloacal exstrophy have increased the success of achieving urinary continence, satisfactory cosmesis, and quality of life. Unfortunately, these procedures are not without their own complications. This review provides readers with an overview of the management of the exstrophy-epispadias complex and potential surgical complications.

Abstract
The exstrophy-epispadias complex is a rare congenital malformation of the genitourinary system, abdominal wall muscles, and pelvic structures. Modern surgical repairs focus on reconstruction of the bladder and its adjacent structures, with the goal of achieving urinary continence, a satisfactory cosmetic result, and a high quality of life. Complex surgery in neonates and young children, as well as a prolonged postoperative course require close collaboration between surgeons, anesthesiologists, intensivists, pediatricians, and an experienced nursing staff. This article will review the spectrum of bladder exstrophy anomalies, the surgical repair, and the perioperative interdisciplinary management.

Abstract
Despite improvements in modern surgical reconstructive techniques, many patients with epispadias-exstrophy continue to experience urinary incontinence. Continent diversion is commonly performed to achieve urinary continence and improve quality of life. In this work we describe the population that can be considered for continent urinary diversion, consider the benefits and implications of concurrent augmentation and bladder neck closure, and review recent literature regarding continence outcomes and common complications. Even in this complex patient population, urinary continence can be reliably achieved by bladder augmentation and the use of intermittent catheterization via a catheterizable cutaneous stoma with or without closure of the bladder neck.

Abstract
OBJECTIVE • To investigate the feasibility of an endoscopic technique as a guide to evaluate bladder outlet resistance during bladder neck plication (BNP) for treatment of female epispadias. PATIENTS AND METHODS • The postoperative outcomes with long-term follow-up of 10 girls with epispadias were reviewed (four had a previous history of bulking agent injection into the BN). • After taking a skin flap from the area between the crura of the bifid clitoris, subsymphyseal dissection was continued to the BN. • Under cystoscopic guidance, BNP was performed using absorbable sutures (two cases) or non-absorbable sutures (eight) aiming to attain a smooth closure of the BN during gradual withdrawal of the cystoscope. • Finally, urethrogenitoplasty was accomplished by urethral reconstruction with tubularization of the inter-clitorial flap followed by monsplasty and approximation of the two hemi-clitorises. RESULTS • The mean (range) follow-up was 9.1 (5-15) years. • After primary surgery seven of the 10 girls were continent and all could void normally. • Of the three failed cases (including two that underwent BNP using absorbable suture), two became dry after injection of bulking agent into the BN and the remaining girl underwent BN reconstruction; she was socially continent at the final follow-up. • Ultimately, all 10 girls were socially continent, including six who were completely dry. • Urodynamic studies showed an increase in mean bladder capacity (P < 0.001) and a significant time-dependent improvement of the leak-point pressure and maximum urinary flow rate. CONCLUSIONS • The present series suggests that single-stage subsymphyseal urethrogenitoplasty together with cystoscopic-guided BNP for management of female epispadias is reliable and effective with definite advantages. • The high success rate and safety of the procedure are important factors for the introduction of this method as a valid option for treatment of this rare congenital anomaly.

Abstract
OBJECTIVES To present our experience of children with epidermolysis bullosa (EB; a rare bullous disorder of the skin) with genitourinary involvement. PATIENTS AND METHODS The medical records of eight children diagnosed with EB (six junctional and two dystrophic type) with genitourinary involvement were reviewed retrospectively. The data collected included age, clinical presentation, ultrasonographic findings, voiding cystourethrography, urodynamic and uroflowmetry studies, and the treatment challenges. The outcomes of the interventions were evaluated every 6 months. RESULTS The mean age was 2.3 years (range 1 day to 7 years). The most common clinical presentations were urinary retention and voiding difficulty. Meatomy was performed in two of three boys followed by diminution of urological complaints. In children with vesico-ureteric reflux, subureteric injections of bulking agent and ureteric stenting were satisfactory. Detrusor instability and bladder compliance improved after α-blocker therapy. The mean (range) follow-up was 62.6 (11-120) months except for two who died in early infancy. CONCLUSIONS Considering the potential urological involvement in every child with EB it is essential to provide patients with early appropriate treatment. Management of urological problems should preferably be in a way to entail minimal interventions and if required be performed using small sized instruments. Medical therapy seems promising for voiding dysfunction in this subset of patients.

Abstract
OBJECTIVES To assess our experience with salvage continence procedures in patients with bladder exstrophy. METHODS We retrospectively reviewed our surgical records of patients with bladder exstrophy who had undergone failed modern staged repair elsewhere and underwent salvage continence operations at our institute from 1996 to 2008. RESULTS A total of 16 patients had undergone salvage continence operations. Bladder augmentation was performed in 11 patients (68.8%); 14 children (87.5%) received a continent, catheterizable stoma. In 6 children (37.5%) bladder neck injections were done. Three patients (18.8%) underwent bladder neck closure combined with other reconstructive procedures. A total of 49 continence procedures were performed, with an average of 3.06 per patient. We included all 16 children >5 years. After these operations, 13 of 16 (81.3%) became continent. Two children were able to void spontaneously and were dry day and night (12.5%). Of the remaining 14 patients, all of whom used clean intermittent catheterization, 11 (68.7%) were continent during the day and night with augmentation and/or a catheterizable stoma. Three patients were incontinent (18.7%). CONCLUSIONS Although the need to perform salvage continence procedures after failed bladder modern staged repair is high, when patients are appropriately selected, continence can be achieved eventually.

Abstract
Exstrophy-epispadias complex (EEC) represents a spectrum of genitourinary malformations ranging in severity from epispadias (E) to classical bladder exstrophy (CEB) and exstrophy of the cloaca (EC). Depending on severity, EEC may involve the urinary system, musculoskeletal system, pelvis, pelvic floor, abdominal wall, genitalia, and sometimes the spine and anus. Prevalence at birth for the whole spectrum is reported at 1/10,000, ranging from 1/30,000 for CEB to 1/200,000 for EC, with an overall greater proportion of affected males. EEC is characterized by a visible defect of the lower abdominal wall, either with an evaginated bladder plate (CEB), or with an open urethral plate in males or a cleft in females (E). In CE, two exstrophied hemibladders, as well as omphalocele, an imperforate anus and spinal defects, can be seen after birth. EEC results from mechanical disruption or enlargement of the cloacal membrane; the timing of the rupture determines the severity of the malformation. The underlying cause remains unknown: both genetic and environmental factors are likely to play a role in the etiology of EEC. Diagnosis at birth is made on the basis of the clinical presentation but EEC may be detected prenatally by ultrasound from repeated non-visualization of a normally filled fetal bladder. Counseling should be provided to parents but, due to a favorable outcome, termination of the pregnancy is no longer recommended. Management is primarily surgical, with the main aims of obtaining secure abdominal wall closure, achieving urinary continence with preservation of renal function, and, finally, adequate cosmetic and functional genital reconstruction. Several methods for bladder reconstruction with creation of an outlet resistance during the newborn period are favored worldwide. Removal of the bladder template with complete urinary diversion to a rectal reservoir can be an alternative. After reconstructive surgery of the bladder, continence rates of about 80% are expected during childhood. Additional surgery might be needed to optimize bladder storage and emptying function. In cases of final reconstruction failure, urinary diversion should be undertaken. In puberty, genital and reproductive function are important issues. Psychosocial and psychosexual outcome depend on long-term multidisciplinary care to facilitate an adequate quality of life.

Abstract
Staged reconstruction repair of bladder exstrophy results in hydronephrosis or renal scarring in 15-25% of patients. A cosmetically acceptable and functional phallus can be achieved in 85% of patients, 20-30% of whom will require more than one operation for penile reconstruction. Episodes of penile glans loss or corporal loss are rarely reported with this technique. Widely disparate results relating to complete urinary continence and volitional voiding have been published, with urinary continence reported to occur in 7-85% of patients. The need for bladder augmentation to obtain urinary continence also varies, with reports that somewhere between 10% and 90% of patients require an augmentation procedure to gain urinary continence. Complete primary repair of bladder exstrophy using the penile disassembly technique results in hydronephrosis or renal scarring in 0-30% of patients, and hypospadias, as a consequence of this repair, will occur in 30-70% of patients. Loss of the glans and corpora appear more frequently with penile disassembly than in staged reconstruction of bladder exstrophy, however, the exact incidence of this complication is unknown. Reported complete urinary continence and volitional voiding rates are also varied following penile disassembly, ranging from 25-65%. A modified bladder-neck reconstruction to gain urinary continence is reportedly required in 15-90% of patients, with 5-10% requiring both bladder augmentation and bladder-neck reconstruction. Experience with complete primary repair of bladder exstrophy, using the penile disassembly approach, seems promising but is not a panacea. To outline the risks and benefits regarding the various surgical techniques for bladder exstrophy, we would recommend the establishment of a national registry for patients with this disorder.

Abstract
Bladder exstrophy is a complex anomaly involving the urinary, genital, and intestinal tracts and the musculoskeletal system. The diagnosis is made typically at the newborn examination or on fetal ultrasonography that is performed by an experienced observer. Management of bladder exstrophy presents several challenges, beginning with initial repair using the more conventional staged approach or the recently re-popularized complete primary repair technique. Major goals in the management of bladder exstrophy are preservation of normal kidney function, close observation for development of adequate bladder function including urinary continence, and provision of acceptable cosmesis and function of the external genitalia. This article provides a brief overview of bladder exstrophy and a detailed description of modern management.

Abstract
OBJECTIVE To review the long-term results of bladder neck reconstruction (BNR) in patients with classical bladder exstrophy or epispadias, and to review the concept of continence surgery in these two groups, stressing the difficulty in finding an adequate balance between urine storage (which implies high outlet resistance and low storage pressure) and complete bladder emptying (which implies low outlet resistance and a transient increase in bladder pressure); surgery cannot achieve 'continence' (which implies active mechanisms) but only 'dryness' (which implies passive mechanisms). PATIENTS AND METHODS Eighty patients with classical bladder exstrophy (52 male, 28 female) and 25 with incontinent epispadias (17 male, 18 female) had their bladder neck reconstructed after a Young-Dees-Leadbetter procedure, subsequently modified by Mollard. The treatment is detailed and results reviewed after a mean follow-up of 11 years. All patients were treated and followed in the same institution. RESULTS In the exstrophy group, 36 (45%) patients presented with a dry interval of > 3 h, with urethral emptying after one BNR; 52 (65%) presented with recurrent urinary tract infections, 19 (24%) with urinary stones, 21 (26%) with dilated upper urinary tracts, 13 (16%) with bladder perforations and one with an adenocarcinoma of the bladder. Thirty-eight patients (48%) required further surgery; 51% of all patients required an endoscopic procedure within 3 months after the BNR and 26% had endoscopic procedures for late (> 3 months) urine retention. In the epispadias group, 13 (52%) patients presented with a dry interval of > 3 h with urethral emptying after one BNR; 12 (48%) had recurrent urinary tract infections, five (20%) upper tract dilatation, two (8%) bladder stones, one (4%) bladder perforation and one an adenocarcinoma of the bowels after a ureterosigmoidostomy. Ten (40%) children required further surgery. CONCLUSION We compared the present results for continence with those in other published series; most complications encountered were related to the obstructive pattern of bladder emptying and the abnormal bladder urodynamic behaviour caused by BNR. We consider that BNR is unpredictable and the roles of the other factors in urinary continence are discussed. Alternative procedures are detailed. The concept of continence surgery in exstrophy and incontinent epispadias is reviewed, stressing the importance of favouring bladder development and limiting obstructive patterns of bladder emptying that cause severe and recurrent complications.

Abstract
PURPOSE We evaluated the impact of reconstructive bladder procedures on the upper urinary tract in bladder/cloacal exstrophy. MATERIALS AND METHODS A total of 57 patients underwent bladder neck procedures for urinary incontinence due to bladder exstrophy between 1988 and 2001. We correlated evidence of renal injury to urinary continence and type of surgery. Renal scarring and moderate/severe hydronephrosis were considered significant upper tract changes. RESULTS Overall 27 patients (47%) underwent bladder neck closure, 38 (67%) augmentation cystoplasty and 44 (77%) a Mitrofanoff procedure. Mean interval since last continence procedure was 4.5 years and mean patient age at last followup was 11.7 years. Hydronephrosis was noted in 18 patients (32%) at last followup (after bladder neck reconstruction in 15). Renal scarring in 14 cases on dimercapto-succinic acid scan was evenly distributed regardless of the type of bladder neck procedure or presence of augmentation. Of 6 patients with grade 3 to 4 hydronephrosis 5 had renal scarring versus only 1 in the 39 without hydronephrosis (p <0.0001). Serum creatinine remained normal in 55 patients, mild renal insufficiency developed in 1 and renal transplantation was performed in 1. Two patients with persistent incontinence are anticipating an augmentation. CONCLUSIONS Of our 57 patients with exstrophy 14 (24%) had significant upper tract damage in the form of renal scarring and/or moderate or severe hydronephrosis. The surgical method of achieving continence was not predictive of hydronephrosis or scarring. Bladder neck closure appears to provide better urinary continence and was equally safe with respect to hydronephrosis or scarring compared to patent forms of bladder neck reconstruction.

Abstract
OBJECTIVE To assess the role of imipramine therapy after bladder neck reconstruction in patients with bladder exstrophy. PATIENTS AND METHODS Seventeen children with bladder exstrophy who achieved partial continence after bladder neck reconstruction received imipramine (1.5-2 mg/kg body weight) for a mean duration of 9.5 months. Assessment before and after therapy included an objective classification of the continence status and artificial slow-fill cystometry. RESULTS Eleven of the 17 patients had a good clinical response to imipramine, with an increase in the continent period to > 2 h, and in nocturnal continence. The urodynamic findings showed a significant improvement in the capacity, end-fill pressure, uninhibited contractions and '20 below' capacity. Only minor side-effects of the drug were reported. CONCLUSION Imipramine has a role in patients who achieve partial continence after reconstruction, and who have a moderately small capacity bladder with poor compliance and uninhibited contractions.

Abstract
OBJECTIVE To evaluate the association of urodynamic variables with continence and upper tract status after reconstruction in patients with classical bladder exstrophy. PATIENTS AND METHODS Thirty-one patients with bladder exstrophy were assessed 1 year after a modified bladder neck reconstruction. The evaluation included a detailed history, radioisotope renography, voiding cysto-urethrography, ultrasonography and artificial slow-filling cystometry. RESULTS Fifteen of the 31 patients were satisfactorily continent; their maximum cystometric capacity was higher than that of the incontinent patients. The compliance, assessed as the maximum bladder capacity at a detrusor pressure of < 20 cmH2O, was significantly higher in the continent patients. There was a 45% incidence of unstable contractions in the 31 patients. Persistent sphincteric activity was detected on electromyography in 10 patients during voiding. Twenty-one patients could initiate a detrusor contraction during voiding. The residual volume was significant in nine of the 21 patients who attempted to void. Patients with a high end-fill pressure (> 40 cmH2O) had a significantly higher incidence of unobstructive hydronephrosis than had patients who had an end-fill pressure of < 40 cmH2O. CONCLUSIONS Bladder abnormalities are common after reconstruction of bladder exstrophy, with poor compliance, small capacity and unstable contractions. These factors hinder any increase in capacity and cause persistent incontinence. Hypocompliance and high end-fill pressure can lead to upper tract damage even in continent patients. Detailed urodynamic evaluation is vital to assess the results and to plan subsequent treatment.
